<p> Name: ______Class Period: ______DNA Model Project th Your DNA Model will be due:__DECEMBER 6 __. Your assignment is to research and build a Double Helix DNA Model. It will count as one test grade (major grade). The maximum grade you can obtain is 110! You will have two weeks to work on it. So, do a great job and don’t put it off until the last minute! I would suggest using wire or pipe cleaners as a framework, and using beads, candies with holes, colored marshmallows, or some other item that you can support on the framework to represent sugars, phosphate groups, hydrogen bond, and the four nitrogenous bases. That means you need seven different colors or shapes, and a way to hold them together and support them. Also, the model must show the helical shape of DNA. Finally, a key must accompany your model. The key must include your name and a representation of each different part of your model that identifies which structural part it represents.</p><p>I do not expect this to be an expensive project, so use what you have. You can make great models using pasta (uncooked), jellybeans, gumdrops, toothpicks, pipe cleaners and a variety of beads. So be creative with this model! Do not use anything that will spoil or create a mess. Do not make it too big. Remember, you have to get it to school in one piece. It should have a minimum of twelve base pairs represented. If you have an idea that doesn’t fit this description, please check with me first to make sure it will work and you will get maximum points. Have fun!! </p><p>GRADING RUBRIC Expectations Possible Points Earned Points 3-D DNA Model  Deoxyribose Sugar 5  Phosphate 5  Hydrogen Bond 5  Nitrogenous Bases Pairing 10 A to T & G & C  Helical shape 5  Free standing or hanging 5  Base Pairs (12 Rungs) 10 Key  Your Name 5  Deoxyribose Sugars 5  Phosphate 5  Hydrogen Bond 5  Adenine 5  Thymine 5  Cytosine 5  Guanine 5 Neatness  Legible (Readable) Key 5  Sturdy 5 Bonus Points (Creativity & 5 Signature) 5 GRADE:</p><p>I acknowledge that I have read the criteria for this project and know that it is worth 30% of my child’s grade (TEST).
